Reply to the 'Comment on "Robust scalable high throughput production of monodisperse drops"' by M. Nakajima, Lab Chip, 2017, 17, DOI: 10.1039/C7LC00181A

This reply to the comment by Nakajima on our article that appeared in Lab on a Chip (E. Amstad, M. Chemama, M. Eggersdorfer, L. R. Arriaga, M. Brenner and D. A. Weitz, Lab Chip, 2016, 16, 4163-4172) highlights the differences between the microchannel step emulsification devices developed by the Nakajima group and the millipede device reported by us in Lab on a Chip.
